Livecode 9 - black screen problem
Hi everyone,
I'm using the new stable LC9 version, and everything looks fine except one thing - the "black screen" problem.
I saw in other topics that this is a known issue, but I didn't find any normal solution for this problem.
In my case, my app works on android 7 and 8 (I checked them on galaxy 7 and 8 ) and every thing looks OK.
But when I checked my app on meizu phone with android 5.1, I just see a black screen.
The only solutions that I'v found in different topics is to set the acceleratedRendering of the stack to false (I don't need to use the "acceleratedRendering" in my app, but I saw this is need to help), and to try to save the standalone in different versions of Android. With or without the "acceleratedRendering" line I get the same result, and for every android version I get the same result.
Please help me to find normal solution for this problem, I need to solve this issue as fast as I can..
Thank you all very much!

Re: Livecode 9 - black screen problem
Update - I checked my app on "Xiaomi redmi pro note 3" with Android 5.1.1 and my app works great.. so I guess that it's not a problem with the Android version, so the problem is with the phone that I use.
So in this case, how do I find a solution for the black screen problem and how can I know in which phones this problem is happening? I can't check my app on all the Android phones...
Any help from someone please?

Re: Livecode 9 - black screen problem
Not for nothing, LiadTal6, but short of precognitive powers, that would indeed be a tough question to answer. My best serious answer is (if you are planning to market this app), put it out there and get feed back from the people that download it.
Re: Livecode 9 - black screen problem
Thanks, but what about fixing this problem?
Is there any way to load the app normally and not just see a black screen?
I would be happy to get any answers from everyone that can help.

Re: Livecode 9 - black screen problem
I'm not sure there is a solution. Android 5 is pretty old, and soon Google Play won't even accept apps that target older versions.
When I first saw this issue it was way back in Android 2.2 and turning off all the radios fixed it ( no wifi, GPS, Bluetooth, etc.) But you can't very well expect your users to do that. The best solution is to require a newer version of the OS, or warn users that your app isn't compatible with all older phones.

Re: Livecode 9 - black screen problem
Hi, I had the same issue with a Huawei Y6 Pro which I bought a year ago with Android 5.1. Deployment of same stack with LC8.1.9 works fine, with 9.0.0 I get the black screen. I would assume that we should be able to deploy to hardware that is a year old. Best. Oliver

Re: Livecode 9 - black screen problem
What is the minimum version you've set in standalone settings? If it's old, try a newer one like Kit Kat or Lollipop.

Re: Livecode 9 - black screen problem
Hi, I made all possible changes in deployment options, nothing so far seems to work, I get the black screeen on my android device (Huawei Y6 Pro, Android 5.1) wheny deploying from LC 9.0. Indy. When deploying from LC 8.1.9. CE everything works fine. Frustratingly many hours went into this.

Re: Livecode 9 - black screen problem
Does the stack use acceleratedRendering? That causes the black screen problem sometimes.

Re: Livecode 9 - black screen problem
Hi and thanks for helping out here,
turning off the accelerated rendering or doing the workaround mentioned in the bug report did not have any effect. I could deploy to another device running android 7.0. Someone mentioned that the black screen issue started after LC 9.0 dp 5 for an Android 5.1 device.
http://forums.livecode.com/viewtopic.php?f=53&t=29384
As mentioned above I can deploy from 8.1.9 without issues, but I need to use the new map widget. I of cause can buy another phone but it is not a good feeling to bring an app out you already know will not work on certain devices.

Re: Livecode 9 - black screen problem
I would like to add that 5.1 might look "old" for the fancy smartphone market... But it is still used on "industrial" devices.
As for myself, as I wrote in other threads regarding the black screen issue, I use a "barcode scanner" (an android terminal with an integrated barcode reader). And it's still sold with 5.1. Why it would be a problem ?
The device is reliable, well built, it does the job perfectly. For this market and this kind of use, we don't need the latest "gadgtets" (i mean who is going to use an IPhone number XXX to do inventory tasks in a dusty, smelly industrial warehouse?)
Let's hope next version of LC 9 could solve this issue.

Re: Livecode 9 - black screen problem
If none of the suggestions work then it's time for a bug report.

Re: Livecode 9 - black screen problem
I follow up : I've installed a test app ( a few native buttons and fields), compiled with LC 9.01 rc1, on my Android 5.1 "barcode scanner" device.
No change : black screen, after launch.

Re: Livecode 9 - black screen problem
Did you report it? The team won't know there's anything wrong unless it's in the database. They may not be able to fix it though if it's limited to that version of Android. I reported a bug that only happened in Android 6.x and they couldn't reproduce it because no one had a device running that version. It worked fine on newer versions.
